[Edit]1.3 to do
a lot -:)
Currently the main focus is to document the positive result and the problem descriptions of the detected problems / bugs.
By authoring a comprehensive problem documentation we structure, verify and rethink the nature of the problem.
Good, exact, detailed, verified problem description is 50% of the solution :-)
Present the solution and problems as input to the readers works.
The introduction chapters currently are rudimentary. Here is more time and effort required.
The main focus is to produce solutions. If we have solutions, we can go to the next step to present the solutions for early adapter. The Feedback improves the solution and the presentation of it.
[Edit]1.4 Usage of SubWiki's
The main purpose of the usage of SubWiki in this document is to keep the main Wiki at a manageable size for the reader and for the authors! The table of contents should contain / display all of the structure. Problem Descriptions are good candidates for SubWiki's. If the description is stored in an SubWiki, you can print the problem description by printing the SubWiki.
An other reason is a technical one: Currenty the size of the main wiki is limited by program restrictions and the wiki has grown to bounce up to this limit :-)

[Edit]2 The Warp Boot Sequence
Basic knowledge about the Warp boot sequence are required. You should know, what your system and you do :-)
Here are some sources to the knowledge:
The warp boot seQunce
[Edit]2.1 Booting from Large Floppy
- Turning on the computer - power good signal from power-supply
- Power On Self Test ( POST ) by the BIOS
- Loading the Bootstrap program in the BR - OS/2 !! SYS01475
- OS2BOOT Loads the operating system loader (skipped with Veits OS2LDR.SEK)
- OS2LDR loads the operating system (kernel)

- The Boot process is complete
[Edit]2.2 Booting from Partitioned Media - Primary Partition - without IBM BMGR Support
- Turning on the computer - power good signal from power-supply
- Power On Self Test ( POST ) by the BIOS
- Loading the Bootstrap program in the MBR - OS/2 !! SYS01475
Looking for the active flag in the Partition Table PT for a flaged primary partition

- The Boot process is complete
[Edit]2.3 Booting from Partitioned Media - Primary / Logical Partition with IBM BMGR Support
- Turning on the computer - power good signal from power-supply
- Power On Self Test ( POST ) by the BIOS
- Loading the Bootstrap program in the MBR - OS/2 !! SYS01475
Looking for the active flag in the Partition Table PT for a flaged primary partition

- The main SHELL, either the Workplace Shell + STARTUP.CMD or just CMD.EXE are started
- The Boot process is complete
[Edit]2.4 The OS/2 Master Boot Record - I13 I13X Test and Flag
The code in the MBR establishes (by calling INT 13H) whether the INT 13H extensions are present. It then leaves a flag in low memory to indicate the presence or absence of support. This flag is used by BM, and by the various boot sectors, to save them doing the same test.
Unless the bootmanager GRUB actually sets that flag (which is, I believe, an OS/2 'thing') then the BM and boot sectors will assume INT 13H extensions are not present...
The actual test is in the MBR:
; Check for presence of INT 13H extensions; if present, set flag at
; 0030:0000 to 'I13X', otherwise set it to 0.
;
SETI13X PROC NEAR
;
MOV AH,41H ; see if INT 13H extensions present
MOV BX,MAGIC2 ; needed too - also DL = drive
INT 13H ; do it
JC SHORT SETI10 ; j if not supported at all
CMP BX,MAGIC ; double check
JNE SHORT SETI10 ; j if not supported
CMP AH,21H ; EDD 1.1 supported?
JB SHORT SETI10 ; j if not
TEST CL,1 ; packet structure device access?
JZ SHORT SETI10 ; j if not supported
MOV EAX,58333149H ; 'I13X'
JMP SHORT SETI20 ; set up for exit
;
SETI10: XOR AX,AX ; store zero for no support
;
SETI20: PUSH INFOSEG ; store at segment 3000:0000 (0030:0000)
POP FS
MOV FS:INF_FLG,EAX ; store it
Author of text snippet is Bob Eager (http://www.tavi.co.uk/os2pages/index.html) in Thread: "Is grub on MBR OK for Linux/OS/2 dual boot" on comp.os.os2.setup.misc 2003-03-30
and author of the DOS Utility EXTDISK (http://www.tavi.co.uk/os2pages/extdisk.html) to display presence of INT 13H extensions
An other interressting snippet from the same tread:
> Trevor Hemsley, Brighton, UK > > How utterly stupid. So if I install something after OS/2 that rewrites > the MBR gratuitously with a copy of its own then my >8GB OS/2 > partition magically stops booting. Sounds like a bug to me. Doesn't > that mean that installing *any* MS o/s post-OS/2 will break it? I > think they _all_ rewrite the MBR on install to one of their choosing. Yes. The silly thing is the code isn't that much smaller anyway. The one place it needs to be small is in the MBR, where there's least room. I wonder if there was some other agenda....like remote booting - that started it. Bob Eager
The test system with Bootmanager Grand Unified Bootloader (GRUB) V 0.97 in BMR behave exactly as Bob predicts.
With GRUB installed in MBR the Bootmanager shows only the systems below the 8 GB limit on the HDD.
see Chapter Bootmanager Grand Unified Bootloader (GRUB) V 0.97
[Edit]2.5 The IBM OS/2 Bootmanager and the boot drive letter
[Edit]2.6 The OS/2 Master Boot Record - I13 I13X Test and Flag versus the Windows Vista BMR
Vista need it own BMR code to work
Here is a source about the Vista boot process and BMR usage
Windows Vista no longer starts after you install an earlier version of the Windows operating system in a dual-boot configuration
http://support.microsoft.com/kb/919529/EN-US/
Currently I do not know a source for MBR code, that do the required steps to OS/2 and Vista both.
The only a very, very limited workaround is to install OS/2 within the 1024 Cly limit of the HDD.

[Edit]3 BIOS Requirements
well, you need a
- Computer with USB BIOS Boot support
This is the BIOS configuration screen of the ThinkPad T23
Bild: USB-Boot-BIOS-Configuration-USB-Support-enable
- An USB MSD device with USB boot support
A hight number of USB sticks does not have this.
See USB Sticks test article in the ref of the Wiki
The CF Card is clearly specified.
So the safest way to boot from USBMSD ( to prevent hardware incompatibility problems )is to use CF Cards and a one slot USB CF Card Reader.
[Edit]3.1 USB BIOS Boot Support Compatibility - Motherboards / Notebooks
I have done some research on this subject and found
a kind of compatibility list on the net

OS/2 MCP2 with current Fixpak and driver level DFSEE version 8.11 or better DANIS506 package R 1.7.10 with Diskinfo UBS Resource Manager
[Edit]6.3 Basic step to create a testsuite
1. create a maintenance partition on my primary HDD with BootAble 4.3
minimum features: only boot to cmd prompt, no wps support
USB Support basic and USBMSD.ADD
System is on Boot Manager Menu
Test the system (drive letter Y:)
2. take a CF Card and create a partition on the medium
How to do it:
data structure of the MSD: Large Floppy or PRM
For the case Large Floppy LVM System see at the step by step instructions in the paragraph
See Wiki Warum erkennt / arbeitet OS/2-eCS nicht mit meinem USB-Speichermedium? (http://os4you.org/wiki-usb-tricks-de.html)
This is the German version of the Wiki.
The English version will follow in the next weeks with the VOICE article
3. There is no drive letter C:, D:, E: on my fixed HDD
The PRM partition has a drive letter of C: in my configuration
The Large Floppy have no assigned drive letter by LVM, no DLAT data structure !
4. Prepare the drive for boot
PRM: Sysinstx C:
Large Floppy: DFSee Version 8.11 or higher
5. xcopy y:*.* c:*.* /H /O /T /S /E /R /V
y: is the drive letter of the mini maintenance system
6. modify the config.sys
7. boot from USB MSD
7.1 Activate USB BIOS support
7.2 change the startup / boot sequence in BIOS
The PRM / Large Floppy is an hard drive for the BIOS
Set the primary hdd to the T23 inactive in boot menu - not in the boot sequence
Bild: USB-Boot-BIOS-Startup-Sequence
[Edit]7 Booting from USB Mass Storage Devices ( MSD )
[Edit]7.1 Booting from USB Diskette
modifying the Service diskettes
Config.sys modifications:
1. rem Floppy
2. set CopyFromFloppy=1
3. Add USB Device drivers
4. special sequence for booting
USBDB.sys must be the first USB statement in config.sys
5. Require options USBDB statement
5.1 /I13 in USBDB.SYS
5.2 no parm /REQ for the driver ....
The set CopyFromFloppy=1
Environment variable must be used for special boot logic in the usb boot process
Without the the SET COPYFROMFLOPPY=1
==> MSG: "OS2 cannot access ..." occurs
Dirty hack?
[Edit]7.1.1 Config.sys for boot from Diskette LVM System
config.sys booting to command prompt ( with only a little cleanup, just from the test bench -:)
Please see SubWiki: Detail Listing config.sys
set bootdrive to usbfloppy with drive letter a: ??????
Who is handling the drive letter a: and B: not DASD / LVM ??
/usage does not work in USB Boot process ???
Drive letters with two legacy floppy drive and 2 USB Floppy
how does this Hardware configuration work ??
Usage of drive letters? only a and b available for floppy devices?
====> Only two floppies per system allowed?
I do see no use of this configuration, but it should work in theory. I have not seen any documented restrictions!
[Edit]7.2 Booting from USB CD-ROM
Currently not test, no USB CD-ROM aviabale
[Edit]7.3 Booting from Large Floppy
[Edit]7.3.1 non LVM Systems
[Edit]7.3.2 LVM Systems
The USB Mass Storage device can be formatted as Large Floppy or as PRM ( Partitioned Removable Media ).
This is the case with formatted as Large Floppy and a system with LVM support
Restriction: It implies FAT16 and Size of MSD less 2 GB.
The basics of the detailed step by step instructions in the following paragraphs are:
1. Wipe the bootsector for a clean, new initialization
2. Write a special boot record to the media
3. Format the media as FAT16 Large Floppy
4. Xcopy of the mini OS/2 system via xcopy /h /o /t /s /e /r /v to the prepared Large Floppy
Now your USB MSD is ready for the test!
Next steps:
1. enable BIOS USB support
2. modify BIOS startup sequence
Now your system is ready for the test, are you ready? :-)
[Edit]7.3.2.1 Howto Prepare a USB MSD as Large Floppy for boot
Please see SubWiki: Howto Prepare a USB MSD as Large Floppy for boot
Thanks to Veit (http://kannegieser.net/veit/index_e.htm) ( OS2LDR.sec ), to Jan (http://www.dfsee.com) ( new functions in DSFee 8.11 ) for the excellent jobs and
to Jürgen (http://www.juergen-ulbts.de/index.de.html) for the tip to have a look at MEMDISK!
[Edit]7.3.2.2 Copy your Mini OS/2 - eCS System from Maintenance Partition to prepared USB MSD
XCOPY x:*.* C:*.* /H /O /T /S /E /R /V
[Edit]7.3.2.3 Config.sys for boot from Large Floppy LVM System
config.sys booting to command prompt ( with only a little cleanup, just from the test bench -:)
Please see SubWiki: Detail Listing config.sys
[Edit]7.3.2.4 Restriction 1: no Drive Letter C: should be used by the LVM Volumes
The following system behaviour / logic is the reason for the restriction:
- The system assigns the drive letter C: to the Large Floppy in the first stage of the boot process.
- C: is the boot drive letter for LVM and the boot process after switching from real to protected mode.
- LVM detects a drive letter conflict, same drive letter on the "fixed" volume and on the "removable" volume
- The removable volume with drive letter C: does not have priority higher than the fixed volume with drive letter C:
- LVM resolves the double assignment of drive letter C:
- LVM assign the next free drive letter to the Large Floppy Device. e.g. drive letter D:
- The boot process switch from real mode to protected mode and continue the boot process with device with boot letter C:
If the fixed disk volume C: contains a valid OS/2 boot system,
the boot process continue with the config.sys from the fixed volume C:
else the boot process failed with message ?????. - If the boot process is successful ( sort of fake success )
the Large Floppy Drive can be accessed at command prompt with the new assigned drive letter.
- First command for the Large Floppy Drive has to be a dir or a chkdsk d: /F command
[Edit]7.3.2.5 Restriction 2: Wiped ( no MBR code/ no LVM Info) primary drive and Large Floppy Booting does not work
Result from testing - with IBM ThinkPad T23 - as of 2009-09-19 Rainer
The boot drive letter C: of the boot device USB Large Floppy Format is obviously not handled correctly in case of a wiped / new Primary HDD without MBR and LVM Code.
The boot steps stopps with the "standard" messages
"OS/2 is unable to operate your hard disk or diskette drive"
A primary HDD with MBR and LVM and no C: drive letter
assigned by LVM to any of the partitions of the primary HDD
and a wiped / new HDD without MBR and LVM Code
does boot form the Large Floppy Format USB boot USBMSD!
The case Booting form Large Floppy with an new HDD as second and do a DFSee cloning HDD DISK1 TO DISK2 does work
[Edit]7.3.2.6 Idea for further development - enhancement
- How to give the drive letter C: preference to a drive letter C: on the fixed disks of the configuration?
This is a most desirable feature. It dismissed the current restriction - no LVM drive letter C: on the fixed disks!
- Can we choose / assign a different / other drive letter to the Large Floppy Device to the default assignment of C:
This is a nice to have feature.
Solution: Filter Driver ?
[Edit]7.4 Booting from Partitioned Removable Media ( PRM )
[Edit]7.4.1 non LVM Systems
The problem is to pass the boot drive letter during the boot process from the Partitioned Removable Media.
Boot Manager does not support PRM.
Howto supply a boot drive letter by booting from PRM.
Well, Danidasd.dmd does have an option for the boot drive.
There are some restrictions of danidasd:
1. Danidasd does not support the LVM info on the HDD.
2. The drive letter for the PRM is assigned by the "old" drive letter assignment method:
first assign a drive letter to all the "fixed" partitions (drives) and than to the "removable" partitions (drive)
the drive letter assigned to the PRM drive is depended from the layout of the HDD of the system to boot
The following system / config.sys on CF Card boots from USB card reader on my T23 system
It is on a FAT file system to keep it simple :-)

[Edit]7.4.2.2 Identifying / Analyse of the Roadblocks for Booting an LVM System from PRM USB MSD Device
In the thread on comp...bugs Mike reported success. He cloned a system ( a system with volume C without boot manager ) to an USB MSD external disk. This cloned system does boot from USB.
This message has been a great motivation to go on with the project. On the other hand I have not been is able to reproduce the reported boot.
Finally I had success. The system boots from the USB drive at the first stage of the USB drive. When switching from real mode to protected mode during the startup, the system does not only switch the mode, it does switch the boot device too! It switches from the cloned USB system to the source system on the fixes hard drive. Both systems are similar / equal, so the switch was not detected during the test.
The case has been detailed documented in the following SubWiki
Please see SubWiki: Detail Case Boot from PRM LVM System Case Fake Success
This case show the feasibility to boot from USB PRM. To understand the nature of the problem it does help a lot.
Two problems has been identified:
1. Tell the system the boot drive letter. For systems without BMGR, if assumes letter c for the primary boot partition. For systems with BMGR, the BMGR assigns a drive letter to each OS/2 boot system on the boot menu. For LVM systems the DLAT info on every bootable partition is evaluated. For non LMV system the drive letter are assign by chronological order of the partition starting with drive letter c.
2. pass the attribute boot drive with the boot drive letter to the LVM / DASD logic.
Currently the boot drive letter does have the attribute "fixed drive". LVM does not except / handle correctly boot drive letters with the attribute "removable".
[Edit]7.4.2.3 Ideas / Concepts for solving the identified problems
[Edit]7.4.2.4 LVM does not process the boot drive letter from an removable device correctly Howto change this?
raw ideas ( as of 2007-02-20 Rainer ):
1. USBMSD.ADD new pram. Handle_First_Removable_as_Fixed_Device
==> Source Code of USBMSD.ADD needed
alternative: CWUSBMSD.ADD
==> ask Chis about modification / development
2. Special patched version of USBMSD.ADD ?
Robert Lalla does a quick first try to patch. Here are the patch and the test results.
Please see SubWiki: Detail Case Boot from PRM LVM System Case USBMSD Patch
3. OS2DASD.DMD New Parm: Handle_First_Removable_as_Fixed_Device
==> Source Code of OS2DASD.DMD needed
4. Filter driver to change type of first removable device to fixed disk
developer with filter drive skill - daniatap.flt as model ?
==> ask Daniela
[Edit]7.4.2.5 Howto Boot a LVM system from a Logical Partition on a PRM USB MSD
How to pass the boot drive letter of an USB MSD boot partition to the system and initiate the boot step process?
Solution: Use ( Alternate ) Boot Manager on a PRM USB MSD
An evaluation of Boot Managers for usage on an USB MSD is done here in the next chapters.
1. IBM OS/2 Boot Manager
2. AiR-BOOT
3. VPART
4. XFDISK
5. GRUB
6. LiLo
7. GAG
[Edit]7.4.2.6 IBM OS/2 Boot Manager
Does not install on PRM by LVM or LVM GUI
Workaround: use DFSee to install primary partition with boot manager on the PRM
Test results:
Boot Manager is loaded by the I13 access from PRM. Now the program logic of the BMGR is processed. Look for an other boot manager partition on the hdds of the system. Found one on the first internal hdd. This one get priority. Look for bootable partitions on the hdd (drive 0 ) to build the list of the boot menu. Look on the second drive ( drive 1 ) for bootable partition. Here the logic fail - It does not look at the PRM, the PRM does not have the BIOS type hdd, if look for a second internal hdd, does not find on and display error Message "Drive 1 not ready, system halted"
Internal boot manager program logic is derived knowledge from comp.os.os2.setup.storage Thread:
- "Drive 2 not ready" error - Warp4 - Dell XPS P200s - Boot Manager (http://groups.google.com/group/comp.os.os2.setup.storage/browse_frm/thread/c889979f273ec13c/42b16149e501cce2?lnk=st&q=os2+boot+manager+drive+not+ready&rnum=2&hl=de#42b16149e501cce2)
This sounds like Boot Manager getting confused by the Bootable
CD support on this machine..
BM asks bios for the drives 80-97, looking for
disk devices, then ready devices..
Apparently the bios answers that the CD is disk and
ready, and then we try to read it and get the not ready error...
Sam Detweiler
IBM OS/2 Device Driver development
Conclusion: Do we have a chance to let the BIOS handle the PRM USB boot device like a HDD?
Question to the experts!!
[Edit]7.4.2.7 Bootmanager AiR-BOOT
The current version is 1.5. The OS/2 installation program AirBoot2.exe is designed to load the manager into the first tack of your primary hard disk, not to the first track of an PRM.
Workaround: Prepare the CF Card with partition loaded with the mini OS/2 test systems and the an directory with the AiR-BOOT program package. Insert the CF card into an IBM Thin Client 8373-S20, boot the system from CF Card and execute the installation program Airboot2 and configure AiR-BOOT. Do test boot on the Thin Client. Shutdown and move the CF Card to the test computer.
AiRBOOT require sector 2 to 60 of the first track of the boot device ( AiRBOOT documentation: developer.txt ).
AiR-BOOT consists of several parts:
- AiR-BOOT MBR Code (sector 1)
- AiR-BOOT Code (starting at sector 2)
- AiR-BOOT configuration (sector 55-59)
- AiR-BOOT MBR backup (sector 60)
Conclusion: MSD devices with tack GEO less than 63 sectors could not be used. CF Card up to 256 MB are of no use. We have to check the GEO before usage.
Next problem: DFSee does not show P-GEO values for PRM, just value zero. This problem is investigated. ==> "CF and GEO Problem"
Work around: Use the ThinkPad UltraBay 2nd HDD Adapter and an CF-to-IDE Adapter
Test results:
1. Feature: does not install on USB MSD
2. AirBoot2 - Installation process, no waring by disk with less than 63 sectors
3. IBM Thin Client 8364S20 and DANIS506.ADD R 1.7.9 does not work -- pip pip pip pip ...
needs special parms or this version is broken for Thin Client chip set
Workaround: Use IBM1S505.ADD
Status as of 2007-02-22: IBM Thin Client 8364S20 and DANIS506.ADD R 1.7.10 works
without any special prams !!
4. IBM Thin Client does not work with CF 1 GB 120x - Hang up in OS2DASD.DMD
Workaround: Use 1 GB CF Card with lower speed
5. AiR-BOOT works on ThinClient !!
6. Test via USB Card Reader and ThinkPad T23
6.1 First boot with AiR-BOOT: Warning Message BIOS changed, Virus?
6.2 Select System to boot, I/O activity on USB MSB, blink of cursor, no OS/2 blob
6.3 Modifies primary system boot sector of internal HDD!
This program feature / behaviour we do not need for our purpose!
A rescue task for DFSee :-)
6. e-mail to developer
Conclusion: The current version ( 1.5 ) of AiR-BOOT is not usable for the task
[Edit]7.4.2.8 Bootmanager VPART
The current version is from 2001-11-08 . The OS/2 installation program VPARTOS2.exe is designed to load the manager into the first tack of your primary hard disk, not to the first track of an PRM.
Workaround: Prepare the CF Card with partition loaded with the mini OS/2 test systems and the an directory with the VPART program package. Insert the CF card into an IBM Thin Client 8373-S20, boot the system from CF Card and execute the installation program VPARTOS2 and configure VPART. Do test boot on the Thin Client. Shutdown and move the CF Card to the test computer.
VAPRT require own code in boot record and sector 11 to 45 of the first track of the boot device ( VPRAT documentation: VPART.DEU ).
The install program VPARTOS2 asks very polite: "May i now write 1 sector in sector 1 and 35 in sectors 11 to 45 ?" :-)
Conclusion: MSD devices with tack GEO less than 63 sectors could not be used. CF Card up to 256 MB are of no use. We have to check the GEO before usage.
Next problem: DFSee does not show P-GEO values for PRM, just value zero. This problem is investigated. ==> "CF and GEO Problem"
Work around: Use the ThinkPad UltraBay 2nd HDD Adapter and an CF-to-IDE Adapter

[Edit]7.4.2.9 Bootmanager XFDISK
Excerpt from History File (http://www.mecronome.de/xfdisk/files/history_en.txt)
XFDisk I Version 0.9.3 Beta EN ============================================================================== History Legend: ------------------------------------------------------------------------------ + Feature added - Feature removed * Bugfix ! Known Bug # Internal change XFDisk I Version 0.9.3 Beta EN ------------------------------------------------------------------------------ * reduced Boot Manager size and moved to end of first head (n sectores/head -> CHS 0/0/n-13 upto 0/0/n). This should solve the problem with HighPoint/Abit IDE adapter cards
This usage of the last sector of the first tack is in conflict with LVM DLAT.
This has to be changed, so no further activities at present. Rainer 2007-03-22

[Edit]7.4.2.12 Bootmanager GAG the Graphical Boot Manager
From the documentation FAQ Question 10
I can't boot OS/2 with GAG. What do I have to do?
GAG can boot OS/2 only if it is installed in a primary partition. If your OS/2 is installed in an extended partition and you want to have the benefits of GAG, you must still use the IBM Boot Manager. To do this, just put the IBM BM timer to zero seconds, and configure the icon of OS/2 to boot the partition where the Boot Manager is stored.
Another problem is when OS/2 is installed in a primary partition in a hard disk that is not the first hard disk. In this case, you must say YES to the option 'Exchange drive letters' when you add the OS/2 partition to GAG. In this case you don't need to use the IBM Boot Manager.
Conclusio:
The IBM Boot Manager does not work from USBMSB, so GAG does not do the job!
[Edit]7.4.2.13 under construction
Well, the results show, booting from Alternate Bootmanager is a possible solution. GRUB demonstrates: The boot from USB MSB via Alternate Bootmanager is possible, AirBoot and VPART does not load from USB, but process the drive letter and LVM stuff correctly under "normal" confidions.
We are working on the case: Boot from USB PRM - LVM System !!
No succes to report - jet :-)
===> *"OS/2 is unable to operate your hard disk or diskette drive"*
Only a some encouraging failures. We learn a lot about the internals!
[Edit]8 Conclusio
1. The booting from USB Diskette LVM System - tested and works
2. The booting from USB CD-ROM - Currently not test, no USB CD-ROM aviabale
3. The booting from Large Floppy non LVM System - not tested, no software configuration aviabale

Base on the currently working case: USB MSD Large Floppy Format and an LVM System Jan has published a condensed instruction set and download at his side (http://www.dfsee.com/dfsee/howto.htm#usbootlf).
Be aware of the prerequisites:
- OS/2 eCS installation with no drive letter C: in use
- Computer with compatible hardware and BIOS
- Compatible USB Mass Storage Devices ( MSD )
Some Words of Wisdom
If you buy new hardware for this application,buy a
- Compatible USB one slot CF Card Reader and CF Memory Cards
The probability to buy a working compatible USB Stick out of the shelf is currently about 50%.

[Edit]9.2.4 Boot without Modification of Preload - the installed Xandros Linux on the Internal Solid Disk
Currently ED Durrant is implementing a system base on the solution from
Chapter 7.4 Booting from Partitioned Removable Media ( PRM ) / 7.4.1 non LVM Systems.
The Mapping definition by the parameter of the DANIDASD.DMD statement is the key to the solution.
BASEDEV=DANIDASD.DMD /BD:D /MT:Aa
Without definition of addional partition types by the /AT parameter, DANIADASD sees / accepts partioniton of following types. The seen (acceptable) partitioned can be mapped to drive letters by the /MT parameter. You can find detail information at the DANIDASD.Doc file of the DANIDASD package found on Hobbes.
DASD manager partition types supported
extended regular
DaniDASD: 05, 0F, 8F 01, 04, 06, 07, 0B, 0C, 0E, [+ other]
Of the 4 partitions (by type ) 83 83 0C ef of the preload, only one partition -the 0C - is accepted and can be mapped to the driver letter C:
So the first primary partition on the SD, the OS/2 Boot partition, is mapped to the drive letter D:
A picture is worth a thousand words
From the Shop of Ed Durrnat :-)
If you do not want to access the primary HDD, just do not map a drive letter to the seen / accepted partition of the HDD
( Has to be tested by ED - Rainer 2008-01-27 )
BASEDEV=DANIDASD.DMD /BD:C /MT:Ba
or
BASEDEV=DANIDASD.DMD /BD:C
Tested by Ed - does not work - "OS/2 cannot ...."
